I have a small ay home leather shop my patterns amd measurements come from both the U.S. and European pattern makers so there’s always a combination of Imperial and metric measurements, at least that’s the two points of this ruler I use. Then there’s the make of the ruler. It’s shaped as a triangle. Important for me because I can hold it with too much worry about my fingers being a risk for my sharp blades. My finger grips are up higher than my cutting point so a slip with the blade has less of a risk of turning my finger tips into a painful ‘encounter. ## Frequently Bought Together - Mr. Pen- Architectural Scale Ruler, Scale Ruler, 12 inch, White, Scale Ruler Contractor, Architect Scal, Scaling Ruler, Drawing Ruler, Architectural Ruler, Rulers for Drawing, Drafting Tools - Mr. Pen- House Plan, Interior Design and Furniture Templates, Drafting Tools and Ruler Shapes for Architecture - Set of 3 - Mr. Pen- Small Architectural Scale Ruler, Aluminium, 6 Inch, 2 Pack, Green and Orange, Pocket Size Ruler, Triangle Ruler, Metal Ruler Set, Architect Scale Ruler for Blueprints --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/70035567-mr-pen-architectural-scale-12-inch-black-scale-ruler-contractor](https://www.desertcart.us/products/70035567-mr-pen-architectural-scale-12-inch-black-scale-ruler-contractor) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-10-14*
